IMPROVEMENT IN STOP-MOTIONS FOR DRAWING-FRAMES.

Specification forming part of Letters Patent No. 205,558, dated July 2,1878; application led May 1l, 1878.

To all 'whom it may @minera Be it known that I, WALTER STUART KEL- LEY,of North VVeare, in the county of Hillsborough and State of NewHampshire, have invented a new and Improved Stop-Motion forDrawing-Frames, of which the following is a specification:

My invention consists in an improved mode of connecting' together thecatch-lever and the trumpet-guide used on a drawing-frame incotton-mills to stop it when the end or sliver breaks or contains fineplaces, the object being to allow of throwing` back the trumpet in aconvenient position for inserting the end or sliver, and to allow ofadjusting the altitude of the free end of the catch-lever to accommodateinequalities in the drawing-frame, as will be hereinafter described.

In the accompanying drawings, Figure l represents a side elevation,partly in section, of my improved stop-motion in position for use on adrawing-frame, the latter being shown in dotted lines. Fig. 2 is adetail section on the line x of Fig. l.

Similar letters of reference indicate corresponding parts.

A is the trumpet-shaped guide, formed on or attached to the forward orupright arm b of the elbow-lever B, which latter is hinged or pivoted bya pin, c, between lugs in the post or standard C, and has its rear flatarm b provided With a vertical circular slot, D, curved from a point orcenter, d, between the said slot D and the fulcrum of the elbow-lever ortrumpet-lever B. At the said point d one end of the catch-lever E ispivoted to the short arm b of the elbow'lever B, the other end beingprovided with the catch e', which, when the breaking or too greattineness of the sliver reduces the friction enough to cause the lever Eto fall, en gages with the ordinary stop-wheel G, and throws oft' thebelt to stop the motion ot' the rollers H and the drawing-frame.

The oscillation or throw of the lever E upon its pivot d in the arm b'is limited by the slot D and a headed stud-bolt, e, which latter isinserted through the slot D, and, with its reduced and threaded end,through a hole or slot, g, in the lever- E, being firmly secured to thelatter by a nut on the opposite side to that from which it is inserted.This allows the shank of the stud e to move freely in the slot D, sothat the guide-trumpet A can be thrown back farther than what isnecessary to cause the catch c to engage with the stop-wheel G, in orderto be in a position convenient for putting the sliver through thetrumpet.

The friction between the sliver and the trumpet is counterpoised by thesliding weight F, securable at any point on the lever E by means of theset-screw j'. In its normal position the lever E is about horizontal andresting by the stud e in the lower end of the slot D, as shown in thedrawing, though its free end may be raised or lowered a little toaccommodate inequalities in the drawing-frame by securing the stud e ata lower or higher point, respectively, in the slot g of the lever E.

The trumpet A is prevented from being drawn by the friction of thesliver too far in between the roller I by a toe or projection', a, onthe elbow-lever B, which limits the movement in the said direction bycontact with a stop, c', on the post C.

Having th us described my invention, Iclaim as new and desire to secureby Letters Patent- The combination of the pivoted catch-lever E, havingthe slot g and the stud e secured therein, and the elbow-lever B, havingthe arm b', provided with a circular slot7 D, with the trumpet A andstandard C, as and for the purpose set forth.
